Specification of Letters Patent.

Patented Jan. 106, 191W..

To all whom t may concern:

Be it known that I, ERNEST E. ASPIN- WALL, a citizen of the UnitedStates, residat Pawtucket, in the county of Provr Machines for Glazingandv Finishing Yarns,-

Threads, and Twines, of which the following is a specification.

This invention relates to certain new and useful improvements inmachines for glazing and finishing yarns, threads and twines, and itpurposes to provide a machine which will operate eiiiciently in applyingsize or finish to yarn,drying and glazing or otherwise finishing thesurface of the yarn subsequent to the application of the size.

The invention further resides in forming the lower size or squeeze rollshollow andV heating the same to stantly warm.

Another object of" the invention is to prokeep the sizing convide abrush roll rotating reversely to the` traverse of the yarn for actingupon the latter.

Other aims will be hereinafter set forth and claimed, the preferredembodiment of the invention being depicted in the drawings wherein-Figures 1 yand la show themachine from one side and in elevation. Figs.2 and 2a depict the machine in elevation from the opposite side thereof.

Referring now to Figs. 1, l?, 2, and 2a, the immersion rollsv 4 and 16are pivotally connected, respectively to vertically movabley rackmembers 30 and 30. ter being joined at their top portions by. a rod 32,the rack members 30 and 30 being slidably disposed in brackets 33 inwhich are journaled drive pinions 34. These pinions mesh with the rackportion of members 30 and 30 and are The immersionA rolls slidey in therespective guides 5-17and are to direct and immerse the yarn inthe sizeor, iinish while the machine is in operation. When the machine is idle,these rolls are elevatedfrom the box so that the yarn will not absorb orcollect an excess of the size or finish and render it harsh or stili'.By inclining the guides the immersion rolls are lowered in proximity toand beneath the size rolls where they combinedly agitate the size orfinish. rllhe disposition of these guides permits of the immersion rollsbeing held against vibratory by links 31, the latrotatable by cranks 35.'f

or swinging movements and, further, provides Sufficient rack members toenable the operative to work about the machine with facility.

The lower size or squeeze rolls 7 andy 19 are hollowl for thecirculation of steam therethrough. Steam is admitted axially throughpipe 36 on one side o the machine and escapes from the opposite sidethroughl pipe 37. Between a pipe 36 and its size roll is a sprocket 38,while a suitable stuffing box 39 1s employed to eliminate leakage of thesize from the size box.

The size rolls are arranged within the size boxes to remove by pressureor to squeeze from the yarns all surplus size or finish, the top rolls 8and. 20 being covered l with a cloth to form a soft cushion to aidl inthe squeezing. Normally, the top size roll is heavy enough to remove allsurplusage when a light iinish is used. However, for a heavy iinishadditional pressure is obtained by a pair of weighted levers 40 pivotedto the main frame 41, as at 42. The main frame is provided with seats 8and 20 in which the top Size rolls are engaged when inoperative so as tokeep the rolls away from the yarns which will hang in suspense andremain free from contact with wet size rolls. The size and linish in theboxes 6 and 18 are kept above a certain temperature in order to keep thematerial in liquid form so that the same will penetrate into and causeitto adhere more firmly to the yarn. The heat necessary for maintainingthe size and finish in liquid form is supplied by means of steam and hotwater. Furthermore, this supplied heat is necessary ito assist theevaporation of the moisture in the size and iinish since moisture ismore easily evaporated when warm than cold.

rlhe wipers which are arranged to the rear the size rolls remove any andall surplus size and iinish as well as lay the fiber onto the yarnsduring movement of the latter and by means of pressure. Y Each anadjustable element 10-22, said elements having angular end flanges orextensions bolted to the upper bars of the frame, the adjustable elementbeing slidably mounted on the main frame through pin and slotconnections 43, as depicted in Fig. 1. The opposing surfaces of thewiper elements are soft and brought together so as to encompass spacebetween they rolls and.,

wiper com-- prises a fixed strip-like element 9-421, and

the yarn to cause the fibers to be drawn back and embedded into the sizeand nish. The wiper elements are separable for passing the yarnstherebetween.

Subsequent to passing between or through the wipers, the yarn isseparated by the scored rolls 12 and 23 which are journaled in bracketsor arms 44 adjustably mounted on arched supports 45. These supports arearranged on the main frame at the ends of the rotary brushes and eachcomprises a flat, strip-like, arcuate body having radial foot portionsextending in opposite directions from its ends for being secured to theupper horizontal bars of frame 41. This arrangement enables thejournaling of the brushes on the frame bars concentric with the archedsupports 45. The rolls 13-25-14 and 26 are likewise adjustably supportedfrom the arched supports by the brackets 46 and 47 which are adjustablecircumferentially of the brushes in spaced arcuate slots formed in eachof said supports. By adjusting these rolls at greater or lesser angles,more or less contact with the brushes is afforded.

The circular brushes 11-24 which are designed to polish the yarns, arerevolved in opposite direction to the traverse of the latter. The mainframe is provided with panels (not shown) for forming an inclosure orchamber in which are located the steam. pipes 48, the latter supplyingheat to warm the brushes to thereby further effect evaporation ofmoisture in the size or nish on the yarn.

Steam pipes 36 and 48 are suitably connected to a source not here shown.

The tension rolls 27 are disposed in vertical slots 50 of standards 51and are driven to draw the yarns from and into the brush so as to createa tension and friction on the latter such as is necessaryI to polish orglaze A the finish and thus eliminate back lashing on the brush whichrevolves in the opposite direction. These rolls are covered with a softcushion to afford a better grip and avoid friction and changtherebetween.

In instances where two sets of size rolls are employed such as isillustrated, the second set of rolls 19-20 are driven to serve thepurpose of tension rolls.

The brushes are driven from a source of power by the belt P and pulleyIl mounted on the shaft of the brush frame 1l', a sprocket being securedto the opposite end of said shaft over which passes the chain 54 to thesprocket 55', causing rotation of the brush frame 24 and the sprocket 58causing rotation of the sprocket 53 by means of the chain 53. The shaftof the sprocket 53 passes across the end of the machine and carries atone side the pulley 52 which causes rotation of the pulley 52 by reasonof the connecting belt, the pulley 52 in turn causing rotation of therolls 27 by reason of the belt 56, pulley 56 and pulley 56". On theopposite end of the shaft of the sprocket is secured the gear 59 whichis in mesh with the gear 60 which drives the chain 57, causing rotationof the sprockets 38-88 and the squeeze rolls 7-19. Suitable tension isapplied to the chain 57 by the roll 61.

In some instances speed changing gearing (not shown) will be employedfor obvious reasons.

Throughout the specification and claims, the word yarns is used tosignify also threads and twines.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is- In a machine of the character described, aframe having spaced upper bars, arcuate strip-like supports havinginwardly and outwardly extending radial foot-portions on their endssecured to the frame bars, each support being provided with a series ofcircumferentially spaced arc-shaped slots, independently adjustablebrackets secured in the support slots-in radial disposition, rollerssupported by the brackets, and a brush iourn aled on the frame barsbetween the foot portions of the arcuate supports and in concentricrelation with the latter.

In testimony whereof I have signed my' name to this specification in thepresence of two subscribing witnesses.

ERNEST E. ASPINWALL.
